What mods must be done to the block, crank, rods, etc. to put a 400 crank in a 350?

have crank main journals ground down to 350 journal diameter.
grind inside of block (oil pan rails & cylinder walls) to clear rods.
replace pistons with a set with the correct pin height.
check/modify oil pan, scraper and windage tray to clear crank & rods.
balance assembly (most probably with 400 harmonic balancer.
I think that is the bare minimum that would be required.
